Fix for Errno::ENAMETOOLONG #37

merged 1 commit into from

4 participants


I added code and spec to shorten filenames that will cause Errno::ENAMETOOLONG on filesystems that will only support 255 characters.

There were a couple other reports of this issue, but their solutions were not up to date with the latest version of ci_reporter.

I made the code compatible with the latest sidestep code and included a spec.


+1 when this occurs it can leave hudson in an unreliable state


Thanks for this. I'll try to get this merged soon. Have a couple other priorities at the moment.

Can you put out a release with this fix please. Thanks.


Sure, 1.6.6 is out and has this fix.
